Question

我有一个包含以下行的nodeJS脚本

import StratumClient from "node-stratum-client"
const client = new StratumClient()

我想让脚本按原样工作，而不更改第一行，这会导致此错误

(function (exports, require, module, __filename, __dirname) { import StratumClient from "node-stratum-client"
                                                              ^^^^^^

SyntaxError: Unexpected token import

所以我按照这里的说明进行操作 - Node error: SyntaxError: Unexpected token import。以下是输出

localhost:node-stratum-client satishp$ npm install --save-dev babel-cli babel-preset-es2015
npm WARN deprecated babel-preset-es2015@6.24.1:   Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update!
npm WARN node-stratum-client@0.0.1 No repository field.

+ babel-cli@6.26.0
+ babel-preset-es2015@6.24.1

src/StratumClient.js -> lib/StratumClient.js
src/StratumClient.test.js -> lib/StratumClient.test.js
src/example.js -> lib/example.js
src/index.js -> lib/index.js

然而，当我再次运行我的脚本时，我得到了同样的错误。如果我上面做错了，我很好奇。我如何知道我的脚本是否使用babel编译？

我如何知道我的nodeJS库是否已使用Babel编译？
